A string of bombings in Pakistan, including a twin suicide attack on a snooker hall used by Shiite Muslims, has left 115 people dead in one of the nation\'s deadliest days in years. At least 82 people were killed and 121 wounded on Thursday when two suicide bombers blew themselves up at the crowded snooker club in an area of the southwestern city of Quetta - dominated by the Shiite community. Earlier Thursday, a bomb detonated under a security forces\' vehicle in a crowded part of Quetta, killing 11 people and wounding dozens more. In a third incident, a bomb exploded at a religious gathering in the northwestern Swat valley, killing 22 people and wounding more than 80, in the deadliest incident in the district since the army in 2009 fought off a two-year Taliban insurgency. Quetta has long been a flashpoint for attacks against Shiites, in particular those from the ethnic Hazara minority, as well as suffering from attacks linked to a separatist insurgency and Islamist militancy.
